Refer to Exercise 9.3. Find the equations of the lines that pass through the points listed in Exercise 9.1.
Exercise 9.3
The equation for a straight line (deterministic model) is
If the line passes through the point (-2, 41, then x = -2, y = 4 must satisfy the equation; that is,
Similarly, if x = 4, y = 6 must satisfy the equation; that is, the line passes through the point (4, 6), then
Use these two equations to solve for ß0, and ß1; then find the equation of the line that passes through the points (-2,4) and (4,6).
Exercise 9.1
In each case, graph the line that passes through the given points.
